As a dream enthusiast, I have to say a few things. First of all, it is assumed that repetitive dreams point to unsolved internal problems.
I think your repetitive dreams are closely linked to your concerns about whether you can fulfill your vital responsibilities. Your old vital responsibilities are the guests of your dream to represent the responsibilities in your current life. Whenever there is a situation that you think you will have difficulty coping with, your dream is the most obvious example of this. For example, if you had worked as a clerk in an office, not a pizzeria, the dream decor would have consisted of an office.
These types of dreams, also known as anxiety dreams, are often triggered by situations that we think will challenge our capacity.
